SKU:: 370564
Molecular Weight:: 16.1
Purity:: ≥90% (SDS-PAGE)
Storage Conditions:: -20°C
Supplier:: United States Biological
Format:: Supplied as a lyophilized powder from 20mM Tris-HCl, 0.5M sodium chloride, pH 8.0, 6% trehalose. Reconstitute with sterile ddH2O to a concentration of 0.1-1mg/ml.
Extra Details:: Involved in countering the first line of host defense mechanisms. Specifically inhibits the response of human neutrophils and monocytes to complement anaphylatoxin C5a and formylated peptides, like N-formyl-methionyl-leucyl-phenylalanine (fMLP). Acts by binding directly to the C5a receptor (C5aR) and formylated peptide receptor (FPR), thereby blocking the C5a- and fMLP-induced calcium responses. Prevents phagocytosis of the bacterium (By similarity). Source: Recombinant protein corresponding to aa29-149 from staphylococcus aureus CHP, fused to 6xHis-Tag at N-terminal, expressed in yeast.
